I have one, GET IT!! It's a bit pricy but well worth it in my opinion. They just added an attachment to mount aftermarket seats, I'll be getting it for Christmas . Right now I use a normal desk chair, I removed the wheels and sat it flat on the floor. It's perfect height for the stand, the stand is adjustable in almost every way so you'll be safe, unless it's too high.
Here's mine, the pic is pretty old, about a year.

Don't mind the clutter , my daughter was only a year old so I had boxes as barricades.
